Human rights in North Korea are, for the most part, nonexistent. Despite numerous rights being de jure guaranteed by the country's constitution, human rights groups such as Amnesty International and nations such as the United States have asserted that in practice, there is no de facto right to free speech, and the only radio, television, music and news providers that are deemed legal are those operated by the government. According to reports from Amnesty International and the U.S. Committee for Human Rights in North Korea, by 2017 an estimated 200,000 prisoners are incarcerated in camps that are dedicated to political crimes, and subjected to forced labor, physical abuse, execution and human experimentation.
